It works well!
I haven't tried all the sound engines, but so far the sound was clean.
What I had forgotten is there is only a right control key, so I couldn't start picoloop. Instead of recompiling, I've just made a little script to change the keymap:
xmodmap -e 'keycode 105 = Control_L'Now I'm recompiling it, and I'll share the binary on the PocketChip forum soon, I think many people like tools such as picoloop (there is SunVox builtin the console).
Here are some screenshots:
